Collapsible Loess Database of Northwest Hebei Region

This dataset collects measured data of collapsible loess from multiple engineering sites in the northwest region of Hebei, China, covering key indicators such as natural water content, dry density, liquid limit, plastic limit, porosity, compression coefficient, compression modulus, sampling depth, and collapsibility coefficient. The data originate from engineering surveys and laboratory tests, and are compiled into a unified format, with missing values checked, outliers verified, and quality controlled. This dataset can be used for identifying collapsible loess, machine learning prediction, regional database construction, and related engineering research.
